The first sign that something was wrong was when I tried to create a new page on the client’s site. The blue Publish button I normally see was replaced with Submit for Review. What the…? That’s what WordPress users with the lowly Contributor role usually see. But I’m an Administrator — the most mighty role known to the world of (single-site) WordPress. (Yes, multi-site installations also confer the fearsome title of Super Admin upon a select few.)

Worse still, if I tried to click Submit for Review, it wouldn’t actually save!

Other problems abounded — I tried to create a new user with Administrator privileges, just to see if my own user account was corrupt. Couldn’t save that, either.

Well, that’s not good. Googling the error didn’t lead to anything immediately helpful, besides this comment that led me to explore the database structure in phpMyAdmin for any problems.

Yes, there were problems. Many of the tables, including wp_options, wp_posts, wp_postmeta and wp_users were missing their primary keys. A bit more digging into the WordPress core showed that, for complex reasons (i.e. I don’t totally get it), without primary keys on these tables, WordPress can’t determine the post type of a new post, and if it can’t determine the post type, it can’t determine the user’s capabilities with regard to that post type, which all comes back to…

Well, a partial solution. Because the database I was working with was not damaged in exactly the same way as the one the OP was working with, I couldn’t use the sample code directly. I had to go through the database and manually create a few primary keys, delete a bunch of auto-draft posts that all had an ID of 0, etc. Then I had to skip a few lines of the OP’s SQL code because they referred to tables that hadn’t lost their keys in my case, for whatever reason. But this is the… key… to solving the problem.

Now then, how did the database get this way? Well, the site lives on a fairly creaky old Fatcow (ugh, that name) shared hosting account, running an old version of MySQL and an almost unrecognizably ancient version of phpMyAdmin. We were undertaking major content changes on the site, so I copied it over to my own sleek, modern staging server running the latest and greatest of everything. The idea was that we’d get all of our changes in place just the way we wanted on the staging server, rather than mess up the live site for 2-3 weeks, and when we were done, we’d just copy everything back over.

Slick. Right? Sure, if both servers are running reasonably identical software versions. Which of course is never the case. Ever.

Apparently when I copied the site back to Fatcow, due to the older MySQL (or possibly phpMyAdmin) version, certain things like the primary keys and auto-increments — and, I’d be willing to bet, but I’m not sure it matters, the collation as well — got lost along the way.
